PURPOSE: To provide a flocculation and separation apparatus capable of efficiently flocculating and separating solid particles or fine oil droplets from a soln. to be treated without using a chemical agent and capable of being constituted of relatively small-sized equipment.
CONSTITUTION: A flocculation and separation apparatus is equipped with a treatment tank receiving a soln. to be treated, a plurality of the electrode plates 5, 6 arranged in the treatment tank so as to leave a predetermined interval therebetween and a power supply device 2 applying AC high frequency voltage across the electrode plate 5, 6 or across the electrode plate 5 and the wall of the tank. A high frequency electric field is allowed to act on the soln. to be treated from the power supply device 2 through the electrode plates to flocculate and separate solid particles from the soln. to be treated.
